Yep. The options above are used for freehubs, not freewheels.
1- You won't be able to use a reverse-threaded track lockring because there's no reverse thread section on your hub. I believe the most common solution here is to use a bottom bracket lockring plus Loctite to keep the cog secure. I've never done this.
2- If your chainline is off enough to need to be fixed, you would do it by respacing the rear axle to move the hub body closer to the drive side. You would then need to re-dish the wheel, adjusting spokes to move the rim toward the non-drive side. I've never done this.
3- Number two might not be necessary. I'm currently running a similar setup, chainring on the inside of the crank spider with a singlespeed freewheel. I'd feel fine about throwing a fixed cog on it.
